The first Ryzen 7000 series desktop CPU from AMD has been announced for PC enthusiasts and gamers that need the highest levels of performance. According to the manufacturer, the top-end Ryzen 9 7950X will be the fastest processor for gaming and content creation in the world. These CPUs support DDR5 RAM and the PCIe 5.0 connector standard and are based on the new "Zen 4" architecture, which also introduces a new platform named AM5. On September 27, the new CPUs will go on sale in stores all across the world. Although prices for India have not yet been disclosed, the flagship 16-core
Priced at $699 is Ryzen 9 7950X. (approximately Rs. 55,360 before taxes). While the 8-core Ryzen 7 7700X has a $399 sticker price (about Rs. 31,600), the Ryzen 5 7600X will cost $299, and the 12-core Ryzen 9 7900X will cost $549 (roughly Rs. 43,480). (approximately Rs. 23,680).
According to claims, the new "Zen 4" architecture performs instructions per clock cycle on average 13% better than the Zen 3 design. Increased cache sizes and improved branch prediction are largely to blame for this. Support for the AVX-512 instruction set results in enhanced performance for applications requiring AI inference.
The Ryzen 9 7950X includes two "core complex" chiplets with 16 cores and 32 threads each, two speeds of 4.5GHz base and 5.7GHz boost, and 80MB of total cache memory. The Ryzen 9 7900 has 76MB of cache memory and 12 cores/24 threads with base/boost frequencies of 4.7GHz and 5.6GHz, respectively. Both are rated at 170W TDP. With 8 multi-threaded cores and a 40MB cache, the Ryzen 7 7700X runs at 4.5GHz but can jump to 5.4GHz. With six cores and twelve threads, the Ryzen 5 7600X operates at 4.7GHz with a boost up to 5.3GHz and 38MB of total cache memory. Both of these CPUs are rated at 105W TDP.
In the future, further Ryzen 7000 series products should be released, filling in the gaps between these and completing the lower end of the stack. Versions with more stacked 3D cache are moreover anticipated to go on sale later. AMD is probably going to keep using older hardware to cater to more frugal customers, especially those who are upgrading and want to keep using their old motherboards and RAM.
Ryzen enthusiast-class CPUs will all feature integrated GPUs for the first time. AMD has chosen to incorporate straightforward RDNA2-based GPUs into the four unveiled models rather than a distinct group of APUs. This should assist with straightforward workloads and diagnostics, while a discrete GPU will still be required for intense games.
A 50% decrease in idle power usage is the consequence of better power management, which incorporates many efficiency enhancements that were originally aimed at mobile CPUs.
In terms of die space and performance per Watt, AMD claims to have a competitive advantage over Intel's 12th Gen "Alder Lake" products thanks to the utilisation of a 5nm TSMC manufacturing process. Performance for single-threaded applications should be better since, according to AMD, Intel's large core counts are the result of the use of a number of lower-powered "efficiency" cores. However, the 13th Gen "Raptor Lake" processor from Intel is also anticipated to be unveiled soon.
AMD asserts that the new generation uses 62 percent less power to achieve the same performance, or 49 percent more performance at the same power level, than the prior generation. Power scaling can go to 74 percent at a 65W TDP, but it only reaches 35 percent at 170W, which is the TDP for the Ryzen 9 7950X.
The long-running AM4 platform's socket compatibility, which dates back to the first generation Ryzen CPU series, is broken by the new AM5 platform. This was required to improve socket power delivery, support DDR5 RAM, and PCIe 5.0. For the first time, AMD switches to an LGA-style package with pins in the motherboard socket and contact pads on the CPU. Existing coolers can still be used without an adapter because the cooler mount has not altered. According to AMD, AM5 will remain supported till at least 2025.
At launch, enthusiast-level motherboards based on AMD's X670 Extreme and X670 chipsets will be offered. Following in October will come the previously unannounced mid-range B650 Extreme and the B650. Only the top-end X670 Extreme supports PCIe 5.0 for discrete graphics and storage, therefore these will differ in terms of feature level.
AMD Expo, a new platform-level tool to optimise DDR5 RAM timings and latency, was also announced by the business. It is said that AMD Expo will improve gaming performance and make overclocking simpler. Last but not least, AMD CEO Dr. Lisa Su hinted at a demonstration of a future Radeon GPU built on the RDNA 3 graphics architecture. These GPUs are expected to come later in 2022 and are believed to have performance per Watt that is 50% greater than the Radeon RX 6000 generation now in use.
